Introduction
==========================================================================

These Release Notes apply to the Eaton SDT CommTool built to include the SCM
Service Version 1 Release 2 for Microsoft C++ 32bit Windows SW Development Platform.

These Release Notes supersede any corresponding information in the Eaton 
Software Development ToolBox Programmer's Guide for the Communications Tool. 

These Release Notes are organized as follows:

   * Documentation

   * Installation

   * Technical Help


Documentation 
==========================================================================

Included on the installation floppy is a copy of the Eaton Software Development 
ToolBox Programmer's Guide for the Communications Tool. The guide is in MS*Word
Version 6.0 format. Also included is the latest Technical Bulletin describing the
Communications Tool's configuration file setup specifically for the SCM.


Installation
==========================================================================

To install the software, simply place the install floppy into your system's 
floppy disk drive and type 

	x:\install y:

where x is the floppy driver letter (either A: or B:), and y is the destination
drive (normally c:).

The installation batch creates an EATON directory off the root of the destination
drive, and INCLUDE, LIB, EXAMPLES, and DOC sub-directories under the EATON
directory.


Technical Help
==========================================================================

This version of the CommTool library was built to support the second version
of the Eaton Satellite Communications Module (SCM). The second version of the
Eaton SCM supports the MDS-II network's 'Basic Services' as well as the 
network's 'Specialized Services' (RTS & UDS).

Included on the floppy (and placed into the EXAMPLES directory) are examples of 
CommTool configuration ('config.ini') files that correctly allow mobile and 
host computers to communicate. 

Upon initialization, the CommTool library reads in the file 'CONFIG.INI', 
from the path specified in the 'COM_PARM_PATH' environment variable, or
from the current directory, if no environment variable is set.

For this release, it is required that the developer is using Microsoft Visual C++
version 4.0 or greater under a 32-bit Microsoft Windows operating system. Also, 
for host (terrestrial) X.25 applications, an X.25 card from Eicon Technologies
(models C21 or S51) is required. 

For COM PORT physical I/O, the library uses GreenLeaf Software's CommLib v5.2
(included on this floppy). For using the Eicon card, the Eicon Technologies 
Developer's ToolKit is used (also included). The Eicon card drivers and card 
configuration software should be included when the card is purchased or can be
obtained from the Eicon web site.
